Security Headers is a part of Snyk, a leading cybersecurity company, and was originally created by Scott Helme! It is a free and easy to use tool designed to help you better deploy and understand modern security features that are available for your website.
Snyk is a comprehensive developer security platform that enables developers to secure their code, open source dependencies, container images, cloud infrastructures, as well as web apps and APIs, all from a single unified platform.
There are services out there that will analyse the HTTP response headers of other sites, but we also have a grading system for results. The HTTP response headers that we analyse provide huge levels of protection, and it's important that sites deploy them. Hopefully, by providing an easy mechanism to assess them, and further information on how to deploy missing headers, we can drive up the usage of security based headers across the Web.
Now that Security Headers is a part of Snyk, it will continue to operate with input from Scott, but also from Snyk's team! This means it has a great assurance of continued, reliable operation for many years to come.
